I am not going to be up long tonight, but i will try and help you make an informed decision.

What exactley is this guns main job going to be?
Daily carry, carry once a week, occasional carry, range plinking, bbq gun? How big of a hand do you have?
Have you ever shot/owned a 1911?
How many rounds a month are you going to shoot it?
Is it going to see any serious use?
Are you planning on modifying it at all?
Why a $1200 budget?
A particular finish your looking for?
3", 3.5", 4", 5", 6" BARREL?

I could go on and on and on with info for the 1911 platform. Answer these questions and then give us a run down of why you want to get into a 1911 platform. I am sure that with the collective minds on here we could help point you into a gun that is going to be better suited to your needs than some of the options you listed above! I am not saying these are not suitable options, i am just saying that i would like to help you get into a better gun for the price range.

Why would you buy a top of the line corvette when an entry level ferrari would be so much better! (hope the analogy makes sense)
